METHOD OF MAKING HEELED HORSESHOES T 0 all whom it may concern:

Be it known that LENooH BOONE, a citizen of the United States, residing at Poughkeepsie, county of Dutchess, State of New York, have invented a certain new and use.

ful Improvement in Methods of Making Heeled Horseshoes, of which the following is a full, clear, and exact description.

My invention relates to improvements in methods of making horseshoes. and has for its object to provide a new and improved method by which heeled horseshoes can be formed from a. straight blank with a single heat. It further has for its object to ex pedite the manufacture of heeled horseshoes by providing a method in which the heel portions are formed when I the blank is straight.

Heretofore heeled horseshoes have been formed on which the heels have been bent up after the horseshoe. has been bent into U shape. This is a more or less difficult proceeding and is liable to result in a more or less uncertain and ununiform product and requires reheating. With my method the product is uniform, the speed is high and the danger of breaking is small. Furthermore with my method the heeled shoes can be formed from a straight blank with but one heat which is a very important factor in the manufacture of horseshoes on account of the expense and delay of reheating. j

The following is a description of my improved method, reference being had to the accompanying drawings, in which,

Fig. 1 shows a straight blank to be subjected to my method;

Fig; 2 shows the blank being bent in a bending machine so as to form the heel portions thereon;

Fig. 3 shows a front elevation of what is shown in Fig. 2;

Fig. 4 shows a plan view of a well known type of horseshoe shaping machine with a heeled blank in position to be bent into U form;

Fig. 5 shows a portion of such machine with the parts actuated so as to partially shape the blank;

Fig. 6 shows a portion of said machine with the parts in a position corresponding to the complete forming of the horseshoe.

Referring more particularly to the drawings 1 is the body and 2-2 are the ends of a straight iron bar constituting a horse- Application filed March 5, 1921. Serial No. 450,001.

shoe blank. In subjecting this bar to my improved method I heat the same and: then place it in the machine shown and described in my application Serial No. 432,390, filed December 22, 1920, this machine being provided with clamping members 3 and 4 which grip the blank where it is to be bent and swaging devices each consisting of a roller 5 mounted in a carrier 6. The carriers 6 are moved upward bending the ends of the blank up against the outer inclined surfaces of the clamping members 4 to form heel portions 2.-2.

These outer surfaces are inclined at an angle to one another so that the inner surfaces 4 of the upturned ends a're inclined in opposite directions relatively to. a plane passing through the body portion of the bar and the axes of the upturned ends. I

Furthermore the rollers 5 are concaveso asto produce convex surfaces upon the outer faces of the upturned ends for the purpose hereinafter described. While "the blankis still hotit is placed in the shaping machine shown in Fig. 4 so as to bear against the abutments 7--7. A longitudinally moving former 8, as it is moved forward by the cam 9, bends the blank, with the heel portions 22 formed thereon, into a U shape about an axis parallel to the axes of said heel portions as shown in Fig. 5 whereupon the'swaging rollers 10, mounted upon the pivoted arms 11 are moved by the wedge cams 12 acting through the links 13 so as to exert a swaging pressure upon the outer surfaces of the legs of the U formed blank,

while the former 8 is finishing its stroke,

forcing it against the opposite sides of the former, beginning at points removed from said ends and progressing toward said ends. This swaging action acts to cause the metal along the outer portions of the legs of the-U, adjacent to the ends thereof,=to flow, with the result that the inclined: surfaces 4: of the heel portions are straightened as at 4 Fig. 6, so as to be substantially at right angles to the axis of the legs of the U at points adjacent to the end portions as shown in Fig. 6.

If the surfaces on the outer faces of the heel portions were straight across this swaging of the blank would produce objectionable extensions or' points upon the ends of the shoe adjacent to the outer surfaces of the legs. In order to prevent this I form ish-H,

convex surfaces 5 upon the outer faces of the heel portions, these convex surfaces being curved about the axes of the heel portions and parallel thereto. When this is done the swaging due to the rollers 10 leaves sult by'using the old form of shaper heretofore used for forming horseshoes without heels.

By the use of my heeling machine above referred to and the use of an ordinary shaping machine I am able to completely form a horseshoe from a straight blank during a l single heating, bending the blank in the heel forming machine and then shaping it while still highly heated, thus securing a complete product with great economy in time, fuel and labor.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In the method of making horseshoes, the improvement which consists in forming a straight blank, bending the ends of said blank into planes at substantially right angles to one surface of the body portion thereof so that the inner faces of said ends are inclined in opposite directions relatively to a plane in which the axes of said ends and body portion lie, bending the product thus formed into a U shape about an axis substantially parallel to the axes of said ends, and then applying swaging pressure to the outer surfaces of the legs thus formed, beginning at points removed from said ends andprogressing toward said ends.

2. In the method of making horseshoes,

the improvement which consists in forming a straight blank, bending the ends of said blank into planes at substantially right angles to one surface of the body portion thereof so that the inner faces of said ends are inclined in opposite directions relatively to a plane in which the axes of said ends and body portion lie, bending. the product thus formed into a U shape about an axis substantially parallel to the axes of said ends, and then applying rolling pressure to the outer surfaces of the legs thus formed, beginning at points removed from said ends and progressing toward said ends.

3. In the method of making horseshoes,

and body portion lie.and the outer faces of said bent ends are convex, and then applying swaging pressure to the outer surfaces of the legs thus formed, beginning at points removed from said ends and progressing toward said ends.

4. In the method of making horseshoes, the improvement which consists in forming a straight blank, bending the ends ofsaid blank into planes at substantially right angles to one surface of the body portion thereof so that the inner faces of said ends are inclined in opposite directions relatively to a plane in which the axes of said; ends and body portion lie and the outer faces of said bent ends are convex, and then applying rolling pressure to theoutersurfaces of the legs thus formed, beginning at points removed from said ends and progressing toward said ends.

5. In the method of making horseshoes, the improvement which consists in forming a straight blank, bending the ends of said iblank so as to form heel portions at substantially right angles to one surface of the body portion thereof and so that the inner faces of said heel portions are inclined in opposite directions relatively to a plane in which the axes of said ends and bodypor tion lie and the outer faces ofsaid heel portions are convex, bending the product thus formed into U shape and then applying swaging pressure to the outer surfaces of the c legs thus formed, beginning at points removed from said ends and progressing to- I ward said ends, said swaging being suflicient to bring said inner faces of said heel portions substantially into planes at right angles to the axisof said body portion adjacent thereto. 7
